Lily Allen is considering becoming a lesbian, confessing she has been having saucy same sex dreams. The pop star is happily dating music mogul boyfriend of three years Seb Chew - but has hinted the dreams have tempted her to experiment. Allen says, "I have been having a lot of lesbian dreams lately. I think I might be gay! Don't tell my boyfriend. I have guy dreams and girl dreams, but the girl dreams are much dirtier."
